- This 60-minute documentary interweaves the development of modern life with innovations in energy technologies in Great Britain and the United States. Coal played a major role from the start, shaping the stage with other fossil fuels by the end of the twentieth century. What will happen in the twenty-first century as we factor addressing concerns about human influence on global climate with the ever-increasing demand for energy and all it provides? Includes expert interviews from Sacramento, CA; Gainesville, FL; Lowell, MA; Minneapolis, MN; New York City, NY; Beulah and Grand Forks, ND; Pittsburgh and Rankin, PA; Dallas and Houston, TX; Arlington, VA; White Salmon, WA; Estavan, SK, Canada; United Kingdom; France; and Sweden.
Renewable resources are important however you are forgetting the manufacturing process causes a spike in CO2
Don't ignore role of coal in modern world. Coal can serve for 200y from now.use of coal will never stop totally.

"Every clean source we know of..." yet no mention of nuclear, by far the cleanest, most compact and environmentally responsible source in every way.
no, they did mention it briefly.
sad to say that it is so unpoplular when it has such potential.
5 years of youtube presence and a mere 9k views. Says a lot about modern desire to expand one's mind. Thank you for the upload!
Very, very nice documentary.
To whom this may concern: When Hurrican Harvey hit we lost power!
You can't back up wind or solar with nuclear or coal generation, these are base load generators and need to run constantly to be economically viable, and they don't have the short flash-up times to allow for a sudden loss of wind or solar power. Only gas can react sufficiently quickly to a power loss. Remember as is stated you need a reserve power source for all wind or solar power as they can both disappear at a moment's notice. Nobody has yet made a success of dealing with renewables and electricity generation, witness the Texas power out of 2021/22, PG&E's power failures and brown outs and likewise for Australia.
sorry, turn off your fox news for a few minutes. most of texas problem was natural gas going offline. renewables are only a small percentage of texas power mix.
don't take may word, check EPRI and EIA.
That's simply not true. Modern coal burning power stations can achieve turndown below 20% and a slew rate of 10% capacity per minute. That's comparable to gas turbines. Nuclear can slew 80% of capacity in 30 seconds in the nuclear navy, better than any source of large thermal power generation.
Coal is dead and I helped kill it .
how so?
